I'm no psychologist, but itcseems yo be a very common theme in the human condition.
First we find a "tribe", maybe it's a sports team, or a computer, or a political party, or a brand of beer. Anything that lets me bond with my peers and lets us be "me and mine", versus "you and yours".
The longer I'm in this group, the more the cycle feeds back, the harder it is to break out.
At some point it's no longer about the common factor. it's about belonging to the tribe. Maybe we got together when say Mercedes was the pinicle of cars. I become a "Mercedes driver". I join a Mercedes club, we do fun runs on Sunday, they're my tribe. Even if (and I'm not saying it is) Mercedes turns into junk, our tribe is still our tribe.
Not wanting to pick a side, but you see this in politics now. For lots of people now it doesn't matter who is running, or what the policies are, it only matters what tribe I'm in. And my tribe is better, the other tribe is rubbish. Those in neither tribe can't understand, because to them both tribes are terrible (perhaps in different ways.)
In the 80s and 90s, the computer platform you chose -was- your identity. Switching from one to another was hard, and socially suicidal. Ideally the switch was done -for- you, not -by- you. My dad's office changed from Apple 2 to PC. Since I couldn't buy my own PC, I got what they got.
But if I had invested my had earned cash in say Apple, it would have been a next to impossible option to just scrap that investment and start over.
Amiga was once way out on top of the pile. By -all- metrics. They were the tribe on top. But it's hard to fall from there and not need to blame someone, or something. It's not the product that failed. It's the people.
